Box 2.4 Criteria for Vulnerable (VU) A taxon is Vulnerable when it is not Critically Endangered or Endangered but is facing a high risk of extinction in the wild in the medium-term future, as defined by any of the following criteria (A to E): A. Population reduction in the form of either of the following: 1. An observed, estimated, inferred or suspected reduction of at least 20% over the last 10 years or three generations, whichever is the longer, based on (and specifying) any of the following: a) direct observation b) an index of abundance appropriate for the taxon c) a decline in area of occupancy, extent of occurrence, and/or quality of habitat d) actual or potential levels of exploitation e) the effects of introduced taxa, hybridisation, pathogens, pollutants, competitors, or parasites 2. A reduction of at least 20%, projected or suspected to be met within the next 10 years or three generations, whichever is the longer, based on (and specifying) any of (b), (c), (d), or (e) above. B. Extent of occurrence estimated to be less than 20,000km 2 or area of occupancy estimated to be less than 2,000km 2 , and estimates indicating any two of the following: 1. Severely fragmented or known to exist at no more than 10 locations. 2. Continuing decline, observed, inferred, or projected, in any of the following: a) extent of occurrence b) area of occupancy c) area, extent, and/or quality of habitat d) number of locations or subpopulations e) number of mature individuals 3. Extreme fluctuations in any of the following: a) extent of occurrence b) area of occupancy c) number of locations or subpopulations d) number of mature individuals C. Population estimated to number less than 10,000 mature individuals and either: 1. An estimated continuing decline of at least 10% within 10 years or three generations, whichever is longer or 2. A continuing decline, observed, projected, or inferred, in numbers of mature individuals and population structure in the form of either: a) severely fragmented (i.e., no subpopulation estimated to contain more than 1,000 mature individuals) b) all individuals are in a single subpopulation D. Population very small or restricted in the form of either of the following: 1. Population estimated to number less than 1,000 mature individuals. 2. Population is characterised by an acute restriction in its area of occupancy (typically less than 100km 2 ) or in the number of locations (typically less than five). Such a taxon would thus be prone to the effects of human activities (or stochastic events whose impact is increased by human activities) within a very short period of time in an unforeseeable future, and is thus capable of becoming Critically Endangered or even Extinct in a very short period. E. Quantitative analysis showing the probability of extinction in the wild is at least 10% within 100 years.

The only African pheasant species has a very fragmented range and is under pressure from hunting. 2.4 Lower Risk species One of the species considered near-threatened, the grey junglefowl of India, has a fragmented global range. © Lynx Edicions © Lynx Edicions 21
